Functional class nomenclature alcohols

Other minor systems are also in use. Some are traditional, and some are very restricted in their application. These include acid nomenclature (inorganic, for oxoacids and derivatives), replacement nomenclature (mainly organic, to denote replacement of skeletal atoms in a parent rather than replacement of hydrogen atoms — oxa-aza replacement is one variant), functional class nomenclature (this is again principally organic and involves the use of type names such as alcohol, acid and ether) and subtractive nomenclatures (such as organic-deoxy and inorganic-debor). These will all be referred to briefly as appropriate. 

Functional class nomenclature (Section 4.1) Type of lUPAC nomenclature in which compounds are named according to functional group families. The last word in the name identifies the functional group the first word designates the alkyl or aryl group that bears the functional group. Methyl bromide, ethyl alcohol, and diethyl ether are examples of functional class names. 

In common functional class nomenclature (Section 2.6) alcohols are called all alcohols such as methyl alcohol, ethyl alcohol, and so on. 

Functional class nomenclature (Section 4.3E) A system for naming compounds that uses two or more words to describe the compound. The final word corresponds to the functional group present the preceding words, usually listed in alphabetical order, describe the remainder of the molecule. Examples are methyl alcohol, ethyl methyl ether, and ethyl bromide. 

These names mix two systems of nomenclature (functional class and substitutive see Section 4.3F). The proper names are isopropyl alcohol (functional class) or 2-propanol (substitutive), and tert-butyl alcohol (functional class) or 2-methyl-2-propanol (substitutive). Names with mixed systems of nomenclature should not be used. 

It is possible to regard radicofunctional nomenclature, in which the functional class narrie of a compound (c.g. alcohol, ketone, etc.) is cited after the names of the attached radicals, as involving an additive procedure (example 146). This type of nomenclature is gradually falling out of use in favor of the substitutive equivalent [for 146 the substitutive name would be l-(3-pyridyl)propan-l-one]. 

Section 4.2 Alcohols and alkyl halides may be named using either substitutive or functional class lUPAC nomenclature. In substitutive nomenclature alkyl halides are named as halogen derivatives of alkanes. The parent is the longest continuous chain that bears the halogen substituent, and in the absence of other substituents the chain is numbered from the direction that gives the lower number to the carbon that...
